- Adding `BaseData.AdjustResolution()` that should return a valid resolution for the given data and security type. This allows us to set a limitation which is useful to avoid invalid data requests or unnecessary fill forward situations. The user will be notified through a console message. - Adding unit and regression test - Updating example algorithms custom data resolution - Some performance improvements. Wont change console color if `SelectedOptimization` is defined
